Part 4

On the edge of each city sit beacons.  One hundred per city.  One hundred metres high.  Landmarks.  Beacons are lit once each month.  Always the last day.  Months are thirty days long.  Days are thirty hours long.  Cleansing is six hours each day. An average human body takes from two to three hours to burn completely.  Candle lasts for two hours.  Each city needs one hundred cleansings for each candle.  Who burns brightest is not down to weight, but body structure.  Cleansing teams have six hours each day.  The cleansing hours are the quietest of each day. Just.  Boots. Heard.
